Rav Aharon Feldman told the bachurim on yom yerushalayim that he agreed saying hallel until the zionists said kochi v’otzem yadi, with their parades showing their “military might”, lhavdil that cannot be said by chanuka which everyone agreed it was a neis they won (the same went for purim)
even with the da’ati community saying hallel and realizing it was a neis, which I believe it was, we only say hallel on nissim where the whole klal yisrael realizes it was a neis, a neis is basically hashem showing his presence, if people dont see it I wouldnt be surprised that we dont say hallel
